MailSenseAI vs HubSpot email tracking
A free, footer-free HubSpot email tracking alternative.
No 200/month ceiling
HubSpot’s free tools stop surfacing open notifications after 200 a month. MailSenseAI never caps opens, clicks, or replies.
Not tied to a CRM seat
Unlimited HubSpot notifications require a paid Sales Hub seat. MailSenseAI Pro is $5/month, standalone.
Built for the sender, not the pipeline
The signal lives in your Gmail sidebar with the follow-up already drafted — no record hygiene required.
MailSenseAI has no notification cap at all. Every open, click, and reply is recorded and shown in real time in the Gmail sidebar on the free plan, with no footer on your emails, and Pro is $5/month — not a per-seat CRM subscription. If you already run your pipeline in HubSpot, the two coexist fine; MailSenseAI is the tracking layer, not a CRM replacement.

FAQ
Questions, answered.
- Is HubSpot email tracking really free?
- It is free to use, but capped. As documented by HubSpot in August 2026, free tools and users without an assigned paid seat receive up to 200 sales notifications per month; past that, the activity feed stops showing new open notifications until the counter resets on the first of the month. Unlimited notifications require a paid Sales Hub seat.
- Is MailSenseAI a free alternative to HubSpot email tracking?
- For tracking, yes — unlimited opens, clicks, and replies on the free plan with no notification ceiling and no footer on your emails. MailSenseAI is not a CRM, so it replaces the tracking layer rather than HubSpot itself.
- Can I use MailSenseAI alongside HubSpot?
- Yes. They are independent — HubSpot keeps your CRM records, MailSenseAI gives you the real-time open/click/reply signal in the Gmail sidebar and drafts the follow-up. Nothing conflicts.
- Does HubSpot add a signature to my emails?
- No, HubSpot does not append a promotional signature, and neither does MailSenseAI. The trackers that do are the Mailtrack/Mailsuite line — see the Mailtrack comparison.
